API posts/update often returns no response

Hi,

I was doing some testing tonight and found that the API requests  
"posts/update" were often not giving me any XML.  Further testing  
showed that it's most like to fail if I wait a few minutes -- the  
first response I get has no XML.  But subsequent requests sent  
immediately this tend to succeed.

In the following run of 14 posts/update requests made via curl, note  
that numbers 1 and 11 failed.  The others succeeded.

It seems that the failures always occur with server fe07, but  
sometimes fe07 works.  Is something broken in Yahoo!-land?
